Description

(57)

The railroad crossing consists of modular elements (1 to 5) with a surface flush with the upper level of the rails (9) and consists of inner center elements (1) and outer center elements (3) on both sides in the rail direction (9). ) are connected by inner outer elements (2), outer left and outer right elements (4, 5). The inner edge elements (2) are terminated on both sides of the passage by the protective part (6). The individual elements (1 to 5) consist of a grate consisting of longitudinal stiffeners (14) and transverse stiffeners (15) on which the support plate (13) is attached to which the metal-metal panel (18) is attached. In the direction of the rails (9), the elements (1 to 5) are terminated by webs (11) with holes (25) for a possible connecting and centering pin (17). The grate and the webs (11) are located on the base plates (12). At the edge of the road body there is a reinforcement (26) of its edge. The reinforcement (26) is L-shaped with a chamfer, is provided with anchorage and adhesive coating.

The invention relates to a level crossing of modular elements having a running surface flush with the upper level of the rails.

Previously known railway crossing constructions are made of wood, metal, concrete, rubber, bitumen or a combination of these materials. Some constructions are modular, but have some disadvantages that limit the use. It is known to use robust frame elements for which special bearing surfaces are required outside and inside the rail body. Known crossings from concrete panels are characterized by high weight, low damping ability to dynamic effects of vehicles and relatively low durability. Compliant function on level crossings can only be achieved with special bearing profiles. However, these solutions have the disadvantages that they only solve, for example, the placement of the panels on the rail foot or web. If the rubber inserts are damaged, the conductive connection of the rails may occur. Or they use closing walls that do not allow mechanical cleaning of the ballast bed, require long time delays due to monolithic foundations and are difficult to set up a level crossing. Tension locks, which pass through the space between the sleepers, prevent mechanical processing. Solid rubber panels are relatively lightweight and dampen the operating effects of vehicles, but their assembly also requires additional elements located at the rails and the rubber manufacturing of these panels is complex. Some constructions, which are finished after assembly, are unsuitable for exposed level crossings. They have a shorter service life and in the event of failure of the rubber flexible fitting at the foot of the rail, an electrically conductive rail connection occurs. If components according to CS AO 184 098 are used, the assembled passage is disadvantageous in terms of dynamic stress. In addition, the parts are robust, heavy, with high production demands. In case of damage to the running surface, it is necessary to disassemble the entire level crossing and replace it.

The above mentioned disadvantages are eliminated by the railway crossing from the modular elements according to the invention, which is based on the fact that in the place of the perpendicular axis of the crossing there are located inner center element and outer center elements, on both sides adjoining outer left and right elements in each case on the last side of the level crossing there is a protective part. The individual elements consisting of two webs, each having at least one opening or a connecting and centering pin, at least one foot plate, support plate and grate of longitudinal stiffeners, cross stiffeners or stiffeners, are provided with a replaceable rubber-metal panel attached to the upper part Supporting plates and lined with webs and closing profiles. An L-shaped edge reinforcement with a chamfer is provided at the end of the road body, provided with anchoring handles and adhesive paint.

The practical implementation of the railway crossing from modular elements is apparent from the attached figures 1-4, where Fig. 1 shows the crossing diagram at a perpendicular neir slightly oblique crossing of the roadway with the railway body. In FIG. 2, this passage is shown in section. Figures 3 and 4 show assemblies of parts for inner center elements or inner edge elements and for outer center elements and outer left or right elements.

The railroad crossing in Fig. 1 consists of an inner central element 1 and on both sides of the adjacent four inner outer elements 2. On the outer sides of both rails are placed outer

The central elements 6 and the adjoining outer left elements 4 and outer right elements 5 at both ends in the direction of the rail are terminated by protective parts 6. These protective parts 6 may be, for example, steel wedges which prevent damage to the passage by loosened connecting rod. railway wagons. The width of the inner elements and the length of the outer elements coincide, and are preferably twice the sleeper spacing module. In order to facilitate orientation, the passage axis 27 is shown in the figure.

FIG. 2 is a cross-sectional view of the assembled level crossing at point A-A shown in FIG. 1. The adjacent roadway is formed of bituminous mass a and gravel bed £. The ballast bed 7 accommodates sleepers 10, preferably made of hardwood. The bituminous mass 6 is terminated by an edge reinforcement 26. The individual edge reinforcements 26 in the lengths of the integral multiple of the length of the outer elements are mounted on the leveled and reinforced layer of bituminous material 6 side by side and fixed to each other by a screw connection in the indicated anchorage holes. The edge reinforcement 26 is preferably positioned with its upper part lower than the finished road surface, which facilitates the overall assembly of the level crossings and creates a V-shaped crack at the point of contact with the level crossing during operation, resistant to further damage. The edge reinforcement 26 itself is L-shaped with a chamfered corner so that it does not touch the front of the sleeper, thereby allowing independent vertical movement of the rail body, including a fixed level crossing. Between the rails 9 there is an inner center element 1 and outside the rails 9 there are outer center elements 3. The center elements 1, 3 abut the base plate 12 on the upper flat surface of the sleepers 10.

Fig. 3 shows an assembly of parts of inner central elements 1 or inner outer elements 2. The support part of each element is a weldment consisting of two webs 11, at least one foot plate 12 and a support plate 13 reinforced from below with a grate of longitudinal reinforcements. 14 and transverse stiffeners 15. In the outer elements 2, in addition, the webs 11, not provided with a base plate 12 and the adjacent stiffener 16, are located in the openings 25 and at least one tapered connecting and centering pin 17 is welded. The recess of the U-shape of the webs 11 allows assembly and handling of the elements. The running surface of the elements is generally formed by at least one weather-resistant rubber-metal panel 18, including a reinforcing plate 19, which serves to securely secure the rubber-panel 18 to the support plate 13 by a screw connection (not shown) into the threaded holes 21. The rubber-metal panels 18 have an elastic end 28 on the rail-side side, which is not provided with a reinforcing plate and, by its shape, facilitates assembly, contributes to stabilizing the position of the fasteners and limits the penetration of dirt into the rail body.

In Fig. 4, the assembly of parts of the outer central elements 3 _r or the outer left or right elements 4, 5 is again shown in a spatial arrangement. at least one tapered engagement and centering pin 17 is closed by openings 25 of the web 11, not provided with a base plate and adjacent reinforcement 16.

The overlap of the uprights 11 above the upper plane of the support plate 13 is lower than the height of the rubber-metal panel 18, which, with a suitably selected overlap of the sidewalls of the rubber-metal panel 18, the surface of the entire level crossing. Replacement of the rubber-metal panels 18, for example in the case of wear or damage to the anti-skid tread, can be carried out without the need to remove the level crossing.

The assembly of the passage itself preferably begins by inserting the inner center element 1 in the center of the roadway crossing with the rail body and attaching it to the sleepers 10, usually by screwing in the mounting holes 24 at both foot plates 12. The outer center elements 3 are fastened in the same way. At a greater angle of oblique crossing, the outer center elements 2 are displaced relative to the inner center element 1 at one rail to the left and the other to the right by the same distance, generally equal to at least one multiple of the sleeper spacing module. This creates the passage base and the other inner edge elements 2, the outer left elements 4 and the outer right elements 5 are fixed sequentially so that their connecting and centering pins 17 are inserted into the holes 25 in the web 11 of the fixed preceding elements, the web 11 of each A new element abuts the base plate 12 of the preceding element. As a rule, the newly mounted element is fastened to the sleeper 10 by screw connection in the mounting holes 24. Preferably, the mounting is carried out simultaneously on both sides from the center of the passage. The disassembly procedure is reversed and there is no damage to the individual elements. Only the left or right part of the level crossing can be dismantled in order to maintain limited road traffic.
